BACKGROUND OF THE INVENTION

1. Field of the Invention The present invention relates to an exercising machine and, more particularly, to an exercising machine with an oblong orbit or cycle.

2. Description of the Related Art

A conventional oblong orbital exercising machine in accordance with the prior art shown in FIG. 1 comprises a main frame 51, an upright post 54 mounted on the front portion of the main frame 51, two swinging handles 55 each having an upper end pivotally connected with the upright post 54, a freewheel 52 mounted on the rear portion of the main frame 51, two pivot members 53 mounted on two opposite sides of the freewheel 52, two links 56 each having a first end pivotally connected with the lower end of a respective one of the swinging handles 55 and a second end pivotally connected with a respective one of the pivot members 53, and two pedals 57 each mounted on a respective one of the links 56.

DETAILED DESCRIPTION OF THE INVENTION

Referring to the drawings and initially to FIGS. 2-6, an oblong orbital exercising machine in accordance with the preferred embodiment of the present invention comprises a main frame 10, an upright post 101 mounted on a front portion of the main frame 10, two swinging handles 13 each having an upper end pivotally connected with the upright post 101, a cycle movement mechanism 11 mounted on a rear portion of the main frame 10, two shafts 12 respectively secured on two opposite sides of the cycle movement mechanism 11, two adjusting units 20 each mounted on a respective one of the shafts 12, two links 14 each having a first end pivotally connected with a lower end of a respective one of the swinging handles 13 and a second end pivotally connected with a respective one of the adjusting units 20, and two pedals 142 each mounted on a respective one of the links 14.

The shafts 12 misalign with each other and are located at different positions of the cycle movement mechanism 11. Each of the shafts 12 is eccentrically mounted on the cycle movement mechanism 11. The swinging handles 13 are located at two opposite sides of the upright post 101.

Each of the adjusting units 20 includes a fixing member 30 mounted on the respective shaft 12 and having a surface provided with a plurality of adjusting holes 31, an adjusting member 40 juxtaposed to the fixing member 30, and a positioning member 41 mounted on the adjusting member 40 and adjustably locked in one of the adjusting holes 31 of the fixing member 30.

The fixing member 30 of each of the adjusting units 20 has a disk shape and is fixed on the respective shaft 12 by a screw.

The adjusting member 40 of each of the adjusting units 20 has a disk shape and is pivotally connected with the second end of the respective link 14. The adjusting member 40 of each of the adjusting units 20 is rotatably mounted on the respective shaft 12 so that the adjusting member 40 of each of the adjusting units 20 is rotatable relative to the fixing member 30. The adjusting member 40 of each of the adjusting units 20 is coaxial with the fixing member 30.

The positioning member 41 of each of the adjusting units 20 is movably mounted on the adjusting member 40 and is detachably mounted in one of the adjusting holes 31 of the fixing member 30. Preferably, the positioning member 41 of each of the adjusting units 20 is pin, latch or bolt.

Each of the adjusting units 20 further includes a connecting member 42 mounted on the adjusting member 40. The connecting member 42 of each of the adjusting units 20 is a rod and is eccentrically secured on the adjusting member 40. The second end of each of the links 14 is provided with a pivot portion 141 pivotally connected with the connecting member 42 of the respective adjusting unit 20. The pivot portion 141 of each of the links 14 is a mounting tube and is mounted on the connecting member 42 of the respective adjusting unit 20.

In operation, again referring to FIGS. 2-6, when a user wishes to operate the exercising machine, he can stand on the exercising machine, with his hands holding and pivoting the swinging handles 13, and with his feet treading the pedals 142 to move the links 14. In such a manner, the links 14 are driven by rotation of the cycle movement mechanism 11 and by pivotal motion of the swinging handles 13 so as to perform an oblong orbit movement so that the user's hands and legs are moved forward and backward in a reciprocal manner so as to exercise his hands and legs. Thus, the links 14 and the adjusting units 20 are driven by the swinging handles 13 to move forward and backward.

In adjustment, referring to FIGS. 7-10 with reference to FIGS. 2-6, the positioning member 41 of each of the adjusting units 20 is detached from one of the adjusting holes 31 of the fixing member 30 so that the adjusting member 40 of each of the adjusting units 20 is unlocked from the fixing member 30 and can be rotated freely. Then, each of the links 14 is moved to drive the adjusting member 40 of each of the adjusting units 20 so that the adjusting member 40 of each of the adjusting units 20 is rotated relative to the fixing member 30 to a determined position. Then, the positioning member 41 of each of the adjusting units 20 is inserted into and locked in another one of the adjusting holes 31 of the fixing member 30 so that the adjusting member 40 of each of the adjusting units 20 is locked onto the fixing member 30 and cannot be moved any more. In such a manner, the positioning member 41 of each of the adjusting units 20 is adjustably locked in any one of the adjusting holes 31 of the fixing member 30, so that each of the links 14 is located at different positions as shown in FIGS. 7-10 to change the positions and angles of each of the swinging handles 13 so as to provide different movement traces, thereby diversifying the exercising effect of the exercising machine.

Accordingly, the adjusting member 40 of each of the adjusting units 20 is rotated relative to the fixing member 30, and the positioning member 41 of each of the adjusting units 20 is locked in any one of the adjusting holes 31 of the fixing member 30, so that each of the links 14 is driven to change the position and angle of each of the links 14 and each of the swinging handles 13 so as to adjust the movement trace of each of the links 14 and each of the swinging handles 13, such that the exercising machine has multiple different movement traces, thereby diversifying and enhancing the exercising effect of the exercising machine.
